Abstract
A method of correcting fluid flow offset for an uncharacterized fluid handling system including a motor. The method includes running the motor at a reference fluid flow demand using generic coefficients, and changing fluid flow demand from the reference fluid flow demand until the motor signals a power limit condition. When the motor signals the power limit condition, the fluid flow demand is noted. The operational fluid flow demands are scaled by a ratio of the noted fluid flow demand to the reference fluid flow demand.

- noting the fluid flow demand when the motor signals the power limit condition;
- and
- scaling operational fluid flow demands to the noted fluid flow demand.
A method of correcting fluid flow offset for an uncharacterized fluid handling system including a motor, said method comprising:
- running the motor at a reference fluid flow demand using generic coefficients;
- measuring actual fluid flow;
- and
- scaling operational fluid flow demands by a ratio of the measured fluid flow to the reference fluid flow demand.
